该工艺采用高效催化剂体系,主催化剂为高效载体催化剂,助催化剂为三乙基铝、给电子体。
UNIPOL工艺具有简单、灵活、经济和安全的特点;该工艺只用很少的设备就能生产出包括均聚物、无规共聚物和抗冲共聚物在内的全范围产品,可在较大操作范围内调节操作条件而使产品性能保持均一。因为使用的设备数量少而使维修工作量小,装置的可靠性提高。由于流化床反应动力学本身的限制,加上操作压力低使系统中物料的贮量减小,使得该工艺比其它工艺操作安全,不存在事故失控时设备超压的危险。
此工艺没有液体废料排出,排放到大气的烃类也很少,因此对环境的影响非常小,与其它工艺相比,该工艺更容易达到环保、健康和安全的各种严格规范。该工艺的另一显著特点是可以配合超冷凝态操作,即所谓的超冷凝态气相流化床工艺(SCM)。该技术通过将反应器内液相的比例提高到45%,可使现有的生产能力提高200%。由于液体含量多少不是流化床不稳定、形成聚合物结块的基本因素,因此该技术关键的操作变量是膨胀床的密度及膨胀松密度与沉降松密度的比例。由于超冷凝态操作能够有效地移走反应热,它能使反应器在体积不增加的情况下提高2倍以上的生产能力,对于投资的节省是非常可观的。
Xitirhisi lexi xi simeka mafambisele ya vuxokoxoko lebyi pfunete, hi xikombiso xa vuxokoxoko lebyi pfunete ku endla mutsari wa mahungu na va vutleketli.
Vutirhisi bya UniPOL byi na swihlawulekisi swa vuxaka, kutirhisiwa ka muxaka, ikhonomi na ku sirheleleka, Xitirhisi lexi endlaka mathulusi yo tala, ku katsa na timhaka ta vanhu lava tolovelekeke, tinyimpi leti landzeleriwaka na switirhisiwa swo karhi. Kusukela eka tinomboro to ntsongo ta switirhisiwa, tindlela to hlengeleta leswaku ku toloveleka ka xitirhisiwa. Hikwalaho ka mahanyelo yo hlahluva mahanyele ya kuvhumba leswaku kuvhumba swilo swo karhi, na vulavisisi byo khotsima kumbe ku cinca loku kulu eka swilo leswi hundzeke.
This process does not discharge liquid waste, and there are very few hydrocarbons discharged into the atmosphere, so the impact on the environment is very small. Compared with other processes, this process is easier to meet various strict standards for environmental protection, health, and safety. Xihlawulekisi lexi hlawulekeke xa mahanyele na vuswikoti byo tirhisa ku endla mintirho leyi rharhanganeke, leswi tiviwaka tani hi ndlela leyi fambisanaka na moya wo hisa. Ithekinoloji leyi endlaka leswaku vanhu vasungule ku andza hikuya hi 200% hi kutlulamisa mahanyele ya moya wokarhi kuya hi 45%. Kusukela hi ndlela leyi kulu eka mahanyele ya mati, a yi hava swilo swo karhi eka ku tumbuluxiwa ka mathlarhi lama hambaneke na vuxokoxoko bya mahungu. Hikwalaho ka ku hlohlotela ndzilo wa hasilo, leswi endlaka leswaku ku antswisa vutivi bya vumunhu hikwalaho ka leswi endliweke emirini yimbirhi.
